A record-setting snowstorm along the Gulf Coast has Louisiana officials worried people unaccustomed to the cold might overreact in ways that could get them killed. Hence, a strange warning was issued during the storm: Don’t invite alligators, bears and other wildlife into your home.

The latest closure means that nearly three-quarters of Louisiana’s portion of the coast-to-coast highway is shut. A rare winter storm brought record snowfall to the state on Tuesday.
